Altium Designer is described as 'PCB Design Software' and is an app in the Education & Reference category. There are more than 25 alternatives to Altium Designer for a variety of platforms, including Windows, Linux, Mac, Online / Web-based and Android. The best alternative is KiCad, which is both free and Open Source. Other great apps like Altium Designer are Fritzing (Paid, Open Source), Autodesk EAGLE (Free Personal), LibrePCB (Free, Open Source) and QUCS (Free, Open Source).
KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras.

KiCad vs Altium Designer opinions
Most users think KiCad is a great alternative to Altium Designer.
Ease of schematic and pcb creating. BOM creation is not very good as excel templates cannot be used so this becomes a largely manual process. Most of the add-on tools cannot be added regardless of what the instructions say. Following the instructions usually ends in some sort of crash. Import/translation tools never install regardless of the instructions. But, with all of that said KiCad is still the best free alternative to Altium Designer.

mcgiwer It's free and provide very good possibilities for circuit and PCB boards design
LibrePCB is a free EDA software to develop printed circuit boards. It’s currently under heavy development to bring out first stable releases as soon as possible.

LibrePCB vs Altium Designer opinions
pros, cons and recent comments
dbrgn The project is still fresh, but very promising. The developers have spent a lot of time thinking about proper a library file format that avoids problems of current open source EDA suites and will make creating and sharing comprehensive parts libraries easier. It is also much better regarding usability than current alternatives like KiCAD.
The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.
